From: Vladimir Oltean <vladimir.oltean@nxp.com> Documentation/networking/switchdev.rst says that VLAN-aware bridges must treat packets tagged with VID 0 the same as untagged. It appears from the documentation that setting the GSWIP_PCE_VCTRL_VID0 flag (which this driver already had defined) might achieve this.
